1. Used to identify and analyze the organizational structure of all kinds of metals and alloy materials.Â
2. It is a binocular-type inverted metallographic microscope Â
3. It can be equipped with photographic device to proceed photomicrography.
4. Due to the surface of specimen coinciding with the table surface, it has no limit to the height of specimen.
5. The equipment base has large supporting area and the arm bend is strong which makes the gravity of equipment lower, thus it can be placed stably and reliably. Â
6. There is a 45 º  tilt angle between the eyepiece and supporting surface, and this make it comfortable to observe. Â
7. It features convenient operation, compact structure and elegant appearance.Â

Description
High efficiency rotray film evaporator (also called rotary scraper evaporator ) consists of one or more cylinders heated with jackets and film-scraper. The film-scraper continuously scrapes the charging material to even liquid film. During the process, components with low boiling points are evaporated and the hangover is expelled from the bottom of the evaporator. Scraper evaporator is a kind of high efficiency machine that achieves falling film and evaporation under vacuum condition.
Application
Teh rotary film evaporator is widely used in chemical, petrifaction, pharmaceutical, pesticide, food and fine chemical industries. This rotary film evaporator is especially suited to thermo-sensitive materials, high viscosity materials and easy crystallization materials.
Features
1. Rotary film evaporator is a new-type high-effective evaporator with high-speed flowing, high-effective heating transfer, short flow time and high operating flexibility.
2. This scraper evaporator features high heat transfer coefficient, high evaporation intensity and short flow time.
3. Rotary film evaporator shares some unique features when compared to the conventional film evaporator, for example, high adaptability, low pressure loss and simple operation.
